Configure Revocation Status Verification of Certificates
The firewall and Panorama use certificates
to authenticate users and devices for such applications as Authentication
Portal, GlobalProtect, site-to-site IPSec VPN, and web interface
access to the firewall/Panorama. To improve security, it is a best
practice to configure the firewall or Panorama to verify the revocation
status of certificates that it uses for device/user authentication.
